🎯 2025 Business Tax Strategy: Pass-through entities (Sole Prop, LLC, S-Corp, Partnership) pay personal tax rates on business profit, while C-Corps pay a flat 21% federal rate. Most businesses need to pay 90% of current year tax OR 100% of prior year tax (110% if prior year AGI > $150K) to avoid underpayment penalties. Self-employment tax is 15.3% (12.4% Social Security + 2.9% Medicare) plus 0.9% additional Medicare tax on income over $200K.
